Konfigurera unmanaged VPS (4 Newbies) - Del 11: Nginx (bättre än Apache) Web Server

Installera Nginx - Nginx logo

Installera och konfigurera Nginx webbserver, tweaking standardfilen struktur, sedan skapa en vhost fil med symbolisk länk är föremål för denna kopiera / klistra in how-to. Så öppna som CLI och jag ska förklara.

Så vi är redo att installera en stjärna attraktion, Nginx (uttalas "motor-x"). Men varför? Inte Apache bäst webbserver?

Apache har tjänat mig väl under många år, både lokalt och på fjärr-värdar, och är fortfarande ett önskvärt val för många stora webbplatser.

Men, kinda like Ubuntu, Firefox och jQuery, det finns en New Kid in Town, och det är smidigare, enklare att konfigurera och använda, och snabbare att tjäna. Ange Nginx webbservern.

Video: Install & Configure Nginx Web Server

Titta på, er, guvideo för en bättre uppfattning om hur man gör detta.

Kolla the_guv s YouTube-kanal på http://youtube.com/guvnrDOTcom

... eller om du inte kan bli störd av det, eller ens om du kan, här är detaljerna ...

Varför välja Nginx? Varför inte Apache eller Lighttpd?

Jag påstår inte att vara expert, bara någon som har forskat extremt noggrant. Jag koncentrerade sig huvudsakligen på de två mest populära, bäst etablerade webbservrar, Apache och Lighttpd och den unge turken alternativ, Nginx, om vilken geekdom är alla aflutter. Här följer en sammanfattning av mina viktigaste resultaten: --

  • Apache är bloatware, lastning outnyttjade moduler som avfall resurser
  • Lighttpd läckor RAM illa
  • Nginx riktmärken snabbast, med minst resurser

Jag har använt denna lätta server för min resurs-tung WordPress blog, guvnr.com, och är imponerad av sin gedigna prestanda. Också viktigt, har det inte att Windows-liknande tendens, en Apache plåga också, så slöseri med resurser genom att köra en massa tjänster som jag inte behöver.

Ta inte mitt ord för det. Du bör inte, eftersom jag inte har utfört några benchmark-tester. Google något liknande Apache vs Nginx "eller Nginx vs Lighttpd och har läst. And here's the Nginx wiki.

Hämta den senaste Nginx Version

Det finns två sätt att installera mjukvara på Linux, använder integrerad installation verktyg eller från källkod.

Normalt installerar vi internt, använder ungefär som Linux installer "aptitude ', men eftersom detta är en så viktig del av vår VPS, jag ska visa dig hur man installerar från källkod. Denna metod tar lite längre tid, men det är värt det eftersom vi har en mycket mer up-to-date version.

.. Med en webbserver, bör vi inte skära hörn. Det skulle vara som att köpa en gul Ferrari.

Först upp, behöver vi en del beroende filer: --

sudo aptitude -y install libpcre3 libpcre3-dev libpcrecpp0 libssl-dev zlib1g-dev

And to create a directory in which to store the Nginx package:-

mkdir ~/sources

Change to that directory:-

cd ~/sources/

Now we get the latest stable Nginx release, nginx-0.7.62 *.

* As of September 2009, edited by the_guv. You should still check it is still the latest, here , and ammend the filename accordingly:-

wget http://sysoev.ru/nginx/nginx-0.7.62.tar.gz

Unzip it:-

tar -zxvf nginx-0.7.62.tar.gz

Go into the new unzipped folder:-

cd nginx-0.7.62

Installing and Testing Nginx

Compile with two options; where to install it, and including 'ssl' (to enable 'https' for secure connections, ie shopping and stuff):-

./configure --sbin-path=/usr/local/sbin --with-http_ssl_module

Install this baby:-

make
sudo make install

Kick it up:-

sudo /usr/local/sbin/nginx

And test it by popping your IP address in a web browser. You should see "Welcome to nginx!"

Now stop it:-

sudo kill `cat /usr/local/nginx/logs/nginx.pid`

Have Nginx Start, Restart or Stop When Required

This is important, for example, upon reboot. We need a script for this. Create a file:-

sudo nano /etc/init.d/nginx

And paste this within:-

#! /bin/sh

### BEGIN INIT INFO
# Provides:          nginx
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts the nginx web server
# Description:       starts nginx using start-stop-daemon
### END INIT INFO

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/local/sbin/nginx
NAME=nginx
DESC=nginx

test -x $DAEMON || exit 0

# Include nginx defaults if available
if [ -f /etc/default/nginx ] ; then
        . /etc/default/nginx
fi

set -e

case "$1" in
  start)
        echo -n "Starting $DESC: "
        start-stop-daemon --start --quiet --pidfile /usr/local/nginx/logs/$NAME.pid \
                --exec $DAEMON -- $DAEMON_OPTS
        echo "$NAME."
        ;;
  stop)
        echo -n "Stopping $DESC: "
        start-stop-daemon --stop --quiet --pidfile /usr/local/nginx/logs/$NAME.pid \
                --exec $DAEMON
        echo "$NAME."
        ;;

  restart|force-reload)
        echo -n "Restarting $DESC: "
        start-stop-daemon --stop --quiet --pidfile \
                /usr/local/nginx/logs/$NAME.pid --exec $DAEMON
        sleep 1
        start-stop-daemon --start --quiet --pidfile \
                /usr/local/nginx/logs/$NAME.pid --exec $DAEMON -- $DAEMON_OPTS
        echo "$NAME."
        ;;
  reload)
      echo -n "Reloading $DESC configuration: "
      start-stop-daemon --stop --signal HUP --quiet --pidfile /usr/local/nginx/logs/$NAME.pid \
          --exec $DAEMON
      echo "$NAME."
      ;;
  *)
        N=/etc/init.d/$NAME
        echo "Usage: $N {start|stop|restart|reload|force-reload}" >&2
        exit 1
        ;;
esac

exit 0

Then give the file permissions and make the script run on reboot, else start/stop/restart when required:-

sudo chmod +x /etc/init.d/nginx
sudo /usr/sbin/update-rc.d -f nginx defaults

nginx.conf - Configuring Nginx

Now open the Nginx configuration file:-

sudo nano /usr/local/nginx/conf/nginx.conf

...and strip out all the content, delete the lot. CTRL-K is the easy way to do that, if you were wondering.

And replace with this:-

user www-data www-data;
worker_processes  4;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    tcp_nopush      on;
    tcp_nodelay     off;
    keepalive_timeout  5;

    gzip  on;
    gzip_comp_level 2;
    gzip_proxied any;
    gzip_types      text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    include /usr/local/nginx/sites-enabled/*;
}

Creating the Virtual Host File Structure & Symlinks

The Nginx file structure is pretty messy for multiple sites, so we'll sort that.

First, layout some new folders:-

sudo mkdir /usr/local/nginx/sites-available
sudo mkdir /usr/local/nginx/sites-enabled

...the first is for our virtual host (vhost) files, the second for their corresponding symlinks which will be referenced by Nginx' config file.

What are vhosts & symlinks?

You have one of each per domain, and one of each for the default settings.

The symlink, or symbolic link, references the web server to the virtual host file.

The vhost file is a configuration file. It tells the web server, for example, things like where the web files live or the kind of URI structure you want.

For now, we need a default vhost file, and that goes in the sites-available folder. So:-

sudo nano /usr/local/nginx/sites-available/default

Now paste this:-

server  {
            listen       80;
            server_name  localhost;
            
            location /  {
                    root   html;
                    index  index.php index.html index.htm;
       			   }
                       
            # redirect server error pages to the static page /50x.html
            error_page   500 502 503 504  /50x.html;
            location = /50x.html 
            		   {
            			root   html;
            		   }
		}

And enable it with this symlink:-

sudo ln -s /usr/local/nginx/sites-available/default /usr/local/nginx/sites-enabled/default

Boot it up again:-

sudo /etc/init.d/nginx start

...and check for that "Welcome..." page again, using your IP in a web browser.

Splendid. All pretty. And pretty well organised.

Moving Along

So that's Nginx up and running.

In Part 12 of this series Set Up an Unmanaged VPS (4 Newbies) I'm taking a quick detour, setting up FileZilla so we've got a Secure FTP (SFTP) connection. That'll be handy to help demonstrate Part 13, when we create another folder structure, this time for our sites and blogs, and pop up a couple of test pages.

Then, in Part 13, I'll show you how to use Subversion to more easily install and upgrade platforms and their modules/plugins. I'll example the popular WordPress scenario - and while we're about it we'll sort out WordPress caching and friendly-URLs.

And then, this, that, the other. Cue index ..
